I was sure they would not be strong enough to make me like them as much as a jet. I am thrilled to have been wrong. The bubbles are shockingly strong and provide a full body massage. You can also learn various ways to sit that let them hit your back in specific places. I actually have come to like the air bubbles more than jets because it gives you the same benefit without any beating that can happen with strong jets.

Unlike traditional spas, inflatable models do not experience many leaks or blockages of tubing. Due to the PVC material, sealing is much easier than with fibreglass and makes these issues less likely to take place. Inflatable tubs are also very simple to access for maintenance, so you will not need to cut or remove any parts of your home in order to get to the area that needs attention.

What you must not forget to do every week is to remove the filter from the hot tub and clean it. Read the user manual that the tub comes with to see where the filter is located, and clean it by simply wiping away the debris that has gathered on it with a cloth or a paper towel while holding it under running tap water. If you notice that large debris has gathered in the tub, immediately check the filter to see if any of that debris is trapped in it to avoid any damage from being done to it.

You can pay up to £1,500 for an airjet inflatable spa, whereas this Lay Z Spa tub comes in at less than a third of that figure. While cheaper spas only fit 2 to 4, this product comfortably sits 4 to 6. The Vegas Hot Tub also has the latest, state of the art massage therapy, quick set up time and tidy design. It also has the advantage of looking great.
One of the people’s main concerns when it comes to owning an inflatable spa is the fact that they do not think that they are ‘up to the job’. Trust me when I say that blow up hot tubs nowadays are better than they have ever been. The quality of the materials used means that you can place them on just about any flat surface and not have to worry about them ‘breaking’.

Once you have the water in you’re ready to heat it up. The digital control panel included with the Coleman Saluspa is easy to use with an automatic start/stop timer-controlled heating system. With a single press of the button to unlock the controls press the heat button to start the heating process press the arrow button to set the temperature required. Place the cover over the tub as that will keep the heat in.

There are all sorts of accessories available for maintaining your portable spa and enhancing the experience, from chemical dispensers to inflatable seat cushions. Any hot tub you consider should include the basic filter cartridges necessary for use, if not an extra filter or two. If you plan to leave the tub filled for days or weeks at a time, you’ll also want one that includes chemicals like chlorine or bromine, along with the necessary dispenser and test strips to monitor the pH levels of the water. Other accessory manufacturers offer a ground mat to protect the bottom of the tub, built-in water softening, and built-in or attachable seat cushions and cup holders.
The maintenance of inflatable hot tubs should be a breeze, right? Keep the filters in good condition by removing and rinsing them every few days or so, depending on how much it has been used. Another downside is the location filters. Some models place the filters inside the heater or pump for easy access, while others put it along the bottom inner portion of the tub. This makes cleaning and changing it a more demanding task.

Bromine does have certain qualities that make it better than chlorine, as discussed in a recent blog, Bromine vs. Chlorine in hot tubs. He points out that bromine is more stable at higher temperatures and pH levels. But most of the argument is made against tablet chlorine, not chlorine generated from salt. Although generated chlorine is still chlorine, it has fewer downsides than using tablet or granular chlorine.

The pump and the hot tub are easy to connect together but you need it to be simple to use while you are in the tub. All the controls are press button, and they are set in a circular style display with a led display in the centre. From the top left there is an auto-lock button which activates in 5 minutes, to release press for 3 seconds. Next is the timer button so you can decide when you want the heater to come on and you can also set the temperature. You have a filter button to turn the filter on and off, a light shows when it is on, you have the option to display the heat in Celsius or Fahrenheit and then there is a heater button to start the heating function, the temperature can be adjusted with the arrow buttons but most people heat it to the maximum 104F. Finally you have the bubble massage button which when pressed automatically turns off the heater. All of these buttons can be accessed from when you are seated in the tub.

Also called ‘fixed,’ ‘traditional,’ and even built-in tubs, regular hot tubs miss the big feature of portability. Portable or movable tubs work for everyone irrespective of how much space you have in your home. You can easily set it up with ease, and in case of an inflatable hot tub, you can store it with utmost ease without wasting any precious real estate.
The amount of time it takes to heat up will all depend on the product you buy, however, they all have electric heaters (not gas). So, the amount of time it takes the portable spa to heat up in comparison to the amount of time it takes the traditional spas to heat up will be longer. After about one hour, the water temperature will increase by 2 or 3 degrees. If you plan on setting the tub up and using it for a long period of time, then this isn’t going to be a downfall. However, if you just want to use it during the weekends, you need to schedule the set-up one day in advance so that the water will be fully heated.
For times when it makes sense to accessorize, the Intex Pure Spa Tub delivers. In addition to a quality six-person heated hot tub, this kit comes with a pump, 170 high-powered bubble jets, separate water filtration system, contoured removable headrest pads and an insulated tub cover.

Once the set is fully inflated, you have to fill it in on your own, making use of a garden hose for example. When the tub is ready to use, you can adjust how much hot you want the water to be and for how long you want it to keep heating. The same goes for the jet heads functioning, all can be adjusted and timed by digital controlling. The main difference between the system of an inflatable and a traditional hot tub is the disposition of the motor/engine that filters, heats and blows water and air. On traditional tubs it will be placed built-in, while on the inflatable one it is a sided appliance.

Even though this SaluSpa Hawaii HydroJet is inflatable it’s made from some strong stuff. The walls are super durable by the layering of a reinforced material like a sandwich between 2 layers of pvc. This protects it from sharp objects and minimises the chance of punctures. As well as the thickness of the pvc it uses I-beam construction in the sides of the hot tub so it has enough stability for you to sit on the edge without it bevelling. This still keeps the comfort factor for when you lean against it while relaxing in the tub.

This model doesn’t only come with bubble jets. It actually has 8 high-powered massage jets installed, which the manufacturer labeled as hydro jets.

The main issue against saltwater hot tubs is that salt causes corrosion. At levels of 2,000-3,000 ppm, there should be no worry about damage to finishes and pool equipment. There is one material in particular that doesn’t like salt, that being Buna rubber, which some pump shaft seals are made of. Again, at normal levels, there should be no concern. But if your pump seal begins to leak, we do have pump shaft seal made for high salt or ozone conditions.

But my water balance is more steady, and the water feels and smells great! The best part? There’s no corrosion damage!

One of the most important factors when purchasing a hot tub is the warranty. Most tubs are built to be portable and comfortable, not necessarily to be durable. Therefore, most manufacturers cover the pump and the heater with a 1-year warranty and the tub pool with a 30-to 90-day warranty. As such, if you are looking to make this kind of an investment, make sure you choose one that offers a longer warranty period. However, with proper care and maintenance, it should last for months even years.

Like many people I know, my first experience with an in-ground hot tub was in a nice hotel on a vacation. I didn’t really know anyone who had these things at home since they’re as expensive as cars and that’s not even counting the operational and maintenance costs. They need a good deal of space too.

One thing to note about the Bestway Miami is that, unlike other inflatable hot tubs in this list, the Miami has bubble jets around only three quarters of the inside cirumference. This means there is a section inside the hot tub where there are no direct bubbles. You still get water swirling around you. Just no direct contact with the bubble jets.
